What group of people was not given the right to vote by either Amendments Thirteen Fourteen or Fifteen?

The 15th Amendment granted suffrage primarily to African-American males by prohibiting discrimination by race (this applied to all previously excluded groups of male citizens); women, residents of the District of Columbia, and young people aged 18-21 weren't granted the right to vote until the 20th century.

The 19th Amendment (1920) allowed women the right to vote; the 23rd Amendment (1961) granted residents of the District of Columbia the right to vote in Presidential elections; the 26th Amendment (1971) dropped the voting age for all citizens from 21 to 18.

The 13th and 14th Amendments had nothing to do with voting.
